Primera entrega de la trilogía de Jacopetti que muestra, utilizando el género documental, extrañas culturas humanas, donde el folklore y las tradiciones se mezclan con la excentricidad, el sadismo y salvajismo expuestos con toda crudeza y autenticidad. Narrada por Stefano Sibaldi.

Secuela oficial del famoso "Mondo Cane", documental donde se muestran extraños comportamientos y rituales de alrededor del mundo.

A new age Mondo film that explores the realm of urban decay and various oddities of the modern world, ranging from underground club scenes to sex change operations.

Taking more inspiration from The Faces of Death than from the "real" movie world, this documentary shows brutal violence, sex, nudes, some curiosities from various countries. Specifically: we observe porn-taxis, gay-pride, erotic patisserie, child prostitution, children forced to crush coca leaves (this causes them horrible wounds on the skin), human skin trade, sick children (very strong scene). According to the tradition of the movie world, even animals are not spared, even if the cruelties against them are limited to two scenes: the extraction of the heart of a monkey while it is still alive, and the operation on the testicles of a other monkey for testosterone.
